Answer 2

B. -7

Explanation:

An atom has a neutral charge with equal numbers of positive and negative particles,

That is, an atom with no chargen or 0 charge is called neutral.

Given,

The ion has a charge of +7,

Also, + 7 - 7 = 0,

Thus, for being neutral the ion needs -7 charge,

Hence, option 'B' is correct.
